before a join session of congress and immediately afterward congress voted for rug declaring war on japan and germany. back to present-day politics, we now know that the u.s. supreme court plans to dive into one of the most talked about and emotional issues of our age. whether same-sex couples have the right to marry. the high court is taking on two cases, one involving the federal defense of marriage act, or d doma, and another involving california's proposition 8, banning same-sex marriages in that state. for analysis into these historic cases, what's going to be a historic hearing, i want to bring in kinji yoshityoshito, professor of constitutional law at new york city. great to see you. >> good to see you. >> put prop 8 aside for a second. do you believe that the supreme court will strike down doma. this is what what you've said. walk me through your thinking on that one. >> y bet. so doma is a really narrow challenge insofar as what the statute does is it says for federal purposes marriages are defined between one man and one woman. so i think it might be best to clarify this by exam
